14. Wolf in the Fold

Kirk takes Scotty to Argelius, a planet renowed for hospitality. Scotty is still recovering from serious injuries accounted to a female member of the crew, so McCoy is concerned he might harbor subconscious resentment toward women. But apparently not; he takes a young woman for a walk through the fog. Kirk and McCoy leave later, and en route to another tavern, hear a high scream. They arrive to find Scotty, bloody knife in hand, standing over the body of the young woman, who has been stabbed dozens of times! They're certain Scotty is innocent despite the evidence, but proving that will require them to discover the actual murderer - and reveal a horrifying truth from history!
